Thanks Michael.

I'm not so sure about VRW being able to do this yet and VRE looks like overkill for my application. I have found an Activex component called AspPDF which should do the job. I have successfully installed the 32 bit version on our 64 bit IIS7.5 server and imported the COM collection into VDF. Now to start testing. The best part about this approach is that I will be able to use the web service code almost unchanged.
